Lucky Block Minigame?

Hi CubeCraft, I have a mini game suggestion for you guys. I think of lucky cubes aka lucky blocks but lucky cubes are cubes that are the same as lucky blocks but kind of fit in with your server. Lucky Cubes would be a game where there is a 10 minute timer and everyone has about a stack of cubes. They basically open them and pvp after 10 minutes. There could be kits like troll cubes or super lucky cubes.
